How San Diego County’s water conservation efforts have prepared them for severe drought conditions

California will absorb the most needed rain this week, following a cool decision from the state to significantly reduce water distribution to the Los Angeles area due to the ongoing drought.

The Los Angeles Department of Water and Power usually takes 40% of its water State water services project, This means that significant reductions can have real economic implications.

The San Diego County Water Department, on the other hand, receives less than 1% of water from the state, significantly different from the 95% it received from the Metropolitan Water District of Southern California in the early 1990s.

How did they get there? Coincidentally, the motive was the threat of a 50% reduction in water allocation due to the drought situation at the time.

“We were finally reduced by more than 30% in 13 months. It had a negative impact on the economy and a negative impact on the quality of life here, and we wanted to experience it again. That really wasn’t the case, “said General Manager Sandy Kerl. Of the San Diego County Waterworks Bureau.

Conservation has become a lifestyle in San Diego. Daily water usage has been reduced by 50% since 1990, consistent with the levels seen during the last drought from 2012 to 2016.

Californians cut water usage by 13% in October.Still late for the goal

But San Diego knew that conservation was only part of the solution. Finding a new water source has become part of the plan, as you can’t save what you don’t have. One of the sources is the Claude “Bad” Lewis Carlsbad desalination plant.

“We need to diversify and have different solutions. We need to bring in water and create new water. That is the role of this facility. We are water from the Pacific Ocean, the largest body of water overall. The world is supplying water from it. In this region, it is water that can be recycled over and over again, “said Jeremy Clutchfield, Water Resources Manager for Utilities. ..

Currently, desalination plants supply 10% of all the water used in the county. It went online in 2015 during the last drought and proved to be a kind of stress test.

“The Carlsbad DeSal plant is a great example of what (desalination) can actually add to the water portfolio to help diversify the water portfolio,” said Michelle Peters, Poseidon Technology and Compliance Manager. I am saying.

“There’s a lot of data and information here that we’re constantly sharing with other agencies above and below the coast that aren’t thinking about desalination. The evidence is in pudding, which means it works,” Clutchfield said. He added.

Another piece of the puzzle will be online at Oceanside this month.

“That’s alarming”: The report shows that 2021 is the driest year in California since 1924.

“We’re actually using what we would otherwise throw away,” said Calidale, director of Oceanside Water Utilities.

Wastewater is captured and treated daily in cities around the world, where instead of draining it into the ocean, 3-5 million gallons of water per day are treated on the Pure Water Oceanside and aquifers. It will be pumped up.

After 3 to 6 months, the treated water will be extracted and delivered to the customer.

“It will provide 30% of the oceanside water supply and, in the long run, will supply 50% of the city’s water demand by 2030, in addition to our recycled water supply project,” Dale said. explained.

One of the more visible efforts was to increase the size of the San Vicente Dam in 2014. The $ 400 million project has increased the size of the dam by 117 feet and nearly doubled the capacity of the reservoir.

In partnership with the City of San Diego, this initiative aims to provide insurance to supply water during periods of extreme drought.

“We set a good example of how we can work together as multiple agencies to ensure that we have enough water to supply us not only for states and countries, but also for the world and when needed. I feel that it is, “said Jeff Schof, chief engineer of the Sam Diego County Water Department.
